IMPROVEMENT IN WHIP-ROUNDING MACHINES.l

Specification forming part of Letters Patent No. 214,257, dated April15, 1879; application filed November 1, 1878.

I To all whom t may concern Beit known that I, HEZEKIAH LOMBARD, ofWestfield, in the county of Hampden and State of Massachusetts, haveinvented certain new and useful Improvements in Whip-Rounding Machines;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangementof a machine for roughing off and finishing whips and similar articlesat one operation, as will be hereinafter more fully set forth.

In the annexed drawings, Figure lis a plan view. Fig. 2 is a face viewof head B, partly 1n section. Fig. 3 is a central vertical section ofthe same. Fig. 4 is a face view of head A; and Figs. 5, 6, 7, and 8 aredetailed views of various parts of my invention.

A A represent the roughingheads, and B B the finishing-heads, the formercontaining five knives each, and the latter sixty, and are so arrangedthat the article being turned will pass between the roughers first, andthen the finishers. For short whips suitable feeding devices should bearranged between them, so

as to more rmly hold and advance them.

The roughing-heads A A are mounted upon inclined arbors or spindles O O,so as to bring the faces through which the blades D project parallelwith each other.

The blades D are set at an angle with relation to the face of the head,and this angle should be such that the blades will neither scrape norgouge out pieces in the whip, but cut them just as desired. The bladesare also inclined with relation to the radii of the head at such anangle as will give them adraw-cut, thereby preventing them from cutting'across the whip, which, if allowed, would have a tendency to spring thewhip down.

Each blade D is held in place by a cap, E, fastened by means of a screw,a, so that by releasing said screw the blade can easily be removed forsharpening. The blade is also p ovided with one or more holes, an, forthe insertion of a pin or projection, b, on the nut d, through which thescrew F lpasses. This screw regulates the distance the edge of the bladewill project to cut properly, and also prevents the blade from beingdriven back by its action on the stock or whip.

The screw F is held infplaceby 1being swiveled in a dovetailed plate, G,insertedin the head, and by turning the screw the nut d will be movedout or in on the screw, carrying the blade with it.

It will be seen that there is no cap on the face of the blade, therebyadmitting of a free delivery of shavings, so that there is no liabilityof clogging, as there otherwise would be, especially if pitch is used tofasten the pieces together, of which a whip is .sometimes composed.

One of the heads A is formed with a projecting hub, I, upon which thearticle being turned must rest if it is small and limber; but, ifsufficiently stiff, it may be held by a guide placed in front. -Theother head A is formed with a corresponding recess,into which the hub Ienters, so as to let the cutters come close together.

The arbors C C of the cutter-heads should be mounted on suitablebearings, so that they may be moved to and from each other, as may berequired, to give the proper shape to the article being turned, and alsothat they may be varied in relation to the angle at which their axis ofrotation may set to the article being turned, forming, however, in allcases au acute angle in front of the cutters and an obtuse angle behindthem.

The blades It It of the finishing-heads are set parallel with their axisof rotation, or at right angles with their faces, so as to scrape ratherthan Whittle, and thus make a smooth surface on the article beingturned.

These blades are set in the heads at an angle to their radius the sameas the roughingblades D, and for the same purpose; but their axes areset nearer horizontal, and the faces are changed correspondingly, so asto set parallel with each other at their tops, which makes them lessconical.

The blades are set into a ring, J, and have a projection, t', which iitsinto a recess in the cutter-head, and another projection, i', 011

which the cap L sits, this cap being drawn down tight by lneans of anut, lc, 011 the end ot' the arbor C', upon which the head is mounted.One ot the caps L forms a hub to support the whip, and the other cap isrecessed to receive said hub.

Having' thus fully described my invention, what I claim as new, anddesire to secure by Letters latent, is-

1. In a machine for rounding whips, the combination of a pair ot'roughing-heads and a pair of finishing-heads, substantially asdescribed, for rouehing and tinishing.;1 a whip at one opera-tion, asherein set forth.

2. The blades ot' the roughing and finishing;` heads, set atan anglewith relation to the axis ot` rotation as weil as in relation to theradius of the heads, substantially as and for the purposes herein setforth.

3. The combination, with the head A, ol' the blade I), having one ormore holes, J, the cap E, plate G, screw F, and nut (I, with projectionb, substantially as and for the purposes set forth.

4. The hub l, formed on one head A, in combination with opposite headprovided with a corresponding recess for the purposes set forth.

5. The combination of the head B, blades h, having projections i i',ring J, and cap L, as and for the purposes herein set forth.

6. The combination of two revolving roughing-heads, arranged in inclinedposition, and provided with adjustable blades set at an anglo to theaxis of rotation and to the radius of the heads, substantially as hereinset forth.

7. The combination of two revolving iinishing-heads, arranged ininclined position, and each provided with a series of blades set at anangle in the face thereof, substantially as herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.
